Beginning with these considerations, we’ve a gearbox with a engine mounting flange that is separable from the housing which incorporate the essential oil seal; in this way we avoid any risk of damaging the essential oil seal in case of alternative of the input flange and the O-Ring can be eliminated.
All the apart covers, swinging and with ft, have O-Rings rather than traditional flat gaskets.
The sizes 03-04-05 allow the rotation of your feet without disassembling them; furthermore the variations with swinging aside covers permit the lateral flanges to be worm gear unit fitted on both sides with simple fixing screws.
The worm screw has a ZI involute profile: with this worm-wheel coupling we shall get a much better performance with a temperature reduction.
The gearboxes and motors are painted with RAL 9022 aluminium colour epoxy powder to protect the parts from oxidation and against micro-blowholes that can come during the pressure of die-castings.
The CHPC pre-stage gears (already within the catalogue of CHM) can also be mounted with this range, finding a gear ratio up to 1 1:300. For larger reductions is possible to have two gears together using an appropriate kit
